So some good news and bad news on my 380 purchase tonight. Ended up grabbing the Sapphire 380 for 279 CAD locally. I could have ordered the Gigabyte for $30 less from NCIX but would have had to wait a week or so to get it and figured a week's worth of waiting isn't worth the missing ETH.
Anyways the gamble paid off I think. The Sapphire has dual 100mm ball bearing fans and a decent backplate. It looks much better built than the Gigabyte. Using Sapphire Trixx I'm able to undervolt it significantly at stock GPU speeds to -80mv and I haven't reached the limit yet. Unfortunately I lost the memory game (or did I?) and ended up with Elpedia instead of Hynix however I'm stable at a 1750Mhz (300Mhz) overclock so far with some room left. So either Elpedia memory has improved or I got lucky. I haven't pushed the card to crash yet but I'm averaging approx 20.5-21.5Mh at these speeds (default is 18.5 or so).
Oh and to add icing I found a $20.00 generic rebate that I should be able to use for the card.
I haven't measured the watts yet at the wall but the card is sipping power (I'll confirm exact wattage later) where the fans are only spinning up to 900 RPM and is dead silent from a few feet away on an open bench.
So pretty happy with my purchase. Still mad I didn't get Hynix but can't complain with a 300Mhz memory overclock so far.
I also ordered from NewEgg another MSI 390 Gaming card as my current one is doing so well.
Fun times. Now it'll be a battle of tweaking all the cards for the best power consumption for 12 cents per KW
Two Fury X's
Two 390's
1 380
1 970
I should be around +-~150Mh all said and done.
Oh and here's a link the Sapphire card if anyone was wondering which model.
